Alliance Sensors Group LRS-18 Series Spring-Loaded LVIT Linear Position Sensor
The LRS-18 series of LVIT (Linear Variable Inductance Transducer) spring-loaded position sensors by Alliance Sensors Group are contactless devices designed for dimensional or position measuring applications in factory automation and in various industrial and commercial applications. They are an ideal solution for when the sensing element cannot be attached to the object being measured. The LRS-18 series offers contactless operation, preventing internal wearout from dithering or rapid cycling, and features an excellent stroke-to-length ratio. The proprietary SenSet field adjustable range scaling allows for easy recalibration.
